• Apache VirtualHost Proxy with a Subdirectory

  - by SuperJer

  Currently, we have an IIS server as our primary web server. We are implementing an Apache server in its place, but still need to have the IIS server accessible. Typically, this is a simple thing, because Apache2 can proxy a subdomain to this server. Our problem, however, is this: we are using dotnetCharting on the IIS server, and the licensing is tied to the domain name. In order to get dotnetCharting to work, another license will have to be purchased. My question is, can Apache2 proxy a subdirectory? For example, can 'www.example.com/subdir' point to the IIS server? It seems like it shouldn't be impossible, but I can't seem to find a solution for this. Any help would be super. Thanks! -Jer

• Windows Update cannot currently check for updates, because the service is not running

  - by Lee

  This morning I attempted to run Windows Update on two of my Windows 7 PCs (both are virtual machines), and I ran into this interesting pop-up error message. I have never encountered this problem before, so I was somewhat perplexed. From the message, my first thought was to see if the Windows Update service was running. It was. As usual, the solution is never so simple. I attempted to restart the service and reboot the PCs to no avail. So, I am off to the interwebs for a solution. I did find a solution to the problem, so I thought to post it for my future reference and for anyone else who may encounter this problem. I will be posting the answer shortly. If you have alternate solutions that have worked for you, please feel free to leave a post or comment.

• PHP shell_exec times out, but not when executed manually

  - by Breck Fresen

  I have a Windows 2008 server with PHP and msys installed. I also have a simple php script that calls shell_exec and tars a few files. When I run the script on my development machine (Windows 7), it works fine. However, when I run it on the Windows 2k8 server, it times out. When I copy and paste exactly what's being run on the cmd line and run it, it executes w/out error in less than a second. One more important detail: when I shell_exec 'dir' or 'netstat', the script runs without any problems. When I shell_exec 'ls' it hangs. When I run ls on the command line, it returns immediately. Other details that might be useful: The Windows 2k8 server is a VPS hosted by Rackspace. I did vanilla installs of Apache, PHP, and msys, but I haven't installed anything else. When I run whoami, I see the php script is executing as the user "nt authority\system".

• Rendering composite/SVideo input with GraphEdit (comp./svid. source for crossbar)?

  - by Synetech

  Does anyone know how to form a GraphEdit graph to render composite/SVideo input (especially for a Hauppauge or AIW card)? Google (and Google Images) finds only results focusing on rendering the TV tuner which is already simple enough. The tv-tuner-in pins connect to the TvTuner/TvAudio source, but nothing seems to be able to connect to the Composite/SVideo pins. I have looked through the filters and could find no sources to connect to the Composite/SVideo input pins of the crossbar; GraphEdit always complains that they are not compatible.

• plesk 9 spamassassin server wide blacklist via cron?

  - by Kqk

  hi, we're running ubuntu 8.04 LTS and plesk 9.2 our simple task is to set up a periodic black list for spamassassin, e.g. using this script .. #!/bin/sh #! Script by AJR to update local spamassassin rules cd /tmp wget -c http://www.stearns.org/sa-blacklist/sa-blacklist.current mv sa-blacklist.current local.cf -f mv local.cf /etc/mail/spamassassin -f rm local.cf -f /etc/init.d/psa-spamassassin restart now, this script runs fine, but plesk doesn't seem to recognize the blacklist in its GUI. which is annoying, especially because plesk itself writes to /etc/mail/spamassassin/local.cf. i wasn't able to find out the secret place, where plesk distinguishes between entries in local.cf added via GUI and command line. any help is appreciated! thanks.

• How do I securely execute commands as root via a web control panel?

  - by Chris J

  I would like to build a very simple PHP based web based control panel to add and remove users to/from and add and remove sections to/from nginx config files on my linode vps (Ubuntu 8.04 LTS). What is the most secure way of executing commands as root based on input from a web based control panel? I am loathe to run PHP as root (even if behind an IP tables firewall) for the obvious reasons. Suggestions welcome. It must be possible as several commercial (and bloated, for my needs) control panels offer similar functionality. Thanks

• How can I create persistent SSH connection to "stream" commands over a period of time?

  - by Darth

  Say that I have an application running on one PC that is sending commands via SSH to another PC on the network (both machines running Linux). For example every time something happens on #1, I want to run a task on #2. In this setup, I have to create SSH connection on every single command. Is there any simple way to do this with basic unix tools without programming custom client/server application? Basically all I want is to establish a connection over SSH and then send one command after another.

• Author Tools for Classroom Material?

  - by user1413

  I'm interested in putting a whole bunch of classroom material online. This material ranges from accounting classes to yoga. I would like to find a simple to use authoring tool that the people who teach the classes can use to put the material online. In other words, I do not want a tool that requires a developer. A person who knows the subject matter and is willing to read the manual should be able to put their material online. At minimum, this tool should allow for text and multi-media to be chained together in a logical form and it should allow quizzes to be created and graded. Even better would be for the tool to have some "smarts" so that subject areas which the student does not understand can be drilled. Even better would be for the tool to have ecommerce built in so that the instructors can charge for the classes. Are there any such tools?

• ubuntu server 10 - slow and can't remove desktop environment

  - by Alex

  i'm running ubuntu server 10.10 with the desktop environment. simple page requests are taking over 5 seconds even when connecting to the server through our local network. i believe this is partially related to having the desktop environment installed, as the server worked faster (but not as fast as it should considering that it's on the local network), but tasksel fails every time (aptitude failed 100). my knowledge of networking and linux in general is limited. would really appreciate ideas on how i can troubleshoot this problem. oh also, in the system monitor, one of the processors is almost always around 100%. i doubt this is normal too....

• Is there a usable HTML web gallery template for Lightroom 2?

  - by Johannes Rössel

  The built-in HTML gallery unfortunately generates invalid HTML markup so its looks are likely more coincidence than proper design. That aside its JavaScript usage prevents using the middle mouse button to open an image in a new tab. A look at the few free HTML gallery templates out there shows me that there seems to be little interest in building an actual HTML gallery which doesn't use JavaScript. Most of them are using JS to build fancy animations or in-page popup boxes containing the image. This may be nice for some people but at least one person who looks at my images is on dial-up and quickly opening all images in individual tabs to let them load and then close the connection is very nice to have there. Anyone seen such a gallery template; i. e. simple, plain HTML without JS? My HTML/CSS skills aren't that good that I can develop such a thing on my own, unfortunately.

• The simplest Ubuntu mail server

  - by John G.

  After days of trying all sorts of tutorials I finally found a simple solution (not necessary the best) for a functional ubuntu mail server: sudo aptitude install postfix next type sudo dpkg-reconfigure postfix and configure like this: Internet Site yourdomain.com john (type your ubuntu user) yourdomain.com, localhost.localdomain, localhost No 127.0.0.0/8 [::ffff:127.0.0.0]/104 [::1]/192.168.0.1/24 (192.198.0.1 replace with your server ip address) 0 + all next install mail-stack-delivery sudo aptitude install mail-stack-delivery At this point you have a working mail server. Next, I configured SquirrelMail and start sending and receaving mail. This configuration worked with both Apache and Nginx.

• How to speed up apache

  - by Zen_silence

  We have a server with 8Cores, 16GB of RAM and RAID 0 SAS 10K drives. Our goal is to use this to serve a fairly simple php application quickly. We have tested all other components and we think we have narrowed it down to apache is our bottleneck. I am no apache guru I have done some research and tested a couple things but when i test with JMeter launching 100 concurrent connections against the server the first 10 - 20 come back quickly 30 - 100ms but the rest take between 1000ms to 3000ms. Anyone have any ideas on what to change in our apache config to make this faster right now its a vanilla install of apache.

• Good Documentation on Avaya IP Office 500 r2 setup

  - by Cliff Racer

  I have set up a couple of Avaya IP Office systems over the course of my current job. I have a pretty good handle on the process, but now I am faced with something I have not done before. Both the IP office systems I have set up used all Digital phones. The new system we are putting in place will actually use IP phones for the first time. After tyring to track down some general documentation on my own, I was not able to find anything that left me feeling comfortable about setting up IP phones on an Avaya IP Office 500. Does anyone know of any good how-To's for setting up IP phones on IP Office? I get the impression its pretty simple but learend enough about Avaya to know that there are some tricky aspects to setting them up

• Create a bootable Ghost CD from a HDD

  - by r0ca

  Hi all, I have a little issue and it may be quite simple to fix. I need to Ghost some computers (locally) and now, it seems to be really hard to have several computers to boot from floppy. Sometimes the floppy is not detected (Old PC) and doesn't boot from it. So I need to create a Ghost image from a HDD. I use Disk to Disk when ghosting from an IDE HDD but I'd like to change it to Disk from Image. My issue is it's a linux, IDE HDD, and I have a laptop with Windows 7. I also have a USB adaptor for IDE HDD. I'm trying to find a way to create a Bootable CD from the HDD connected on my laptop with the USB adaptor. Is it possible to do this? What would be the best way to do that?

• Creating svn repo programmatically from a webpage and sudo

  - by Adriano Varoli Piazza

  We want to automate the creation of the svn repos and trac environments for new projects. Basically, this would mean creating a web script that got some info (like env and repo name, etc) from the user and then executed sudo -u svn svnadmin create /var/svn/<projectname> trac-admin /var/trac/sites/<projectname> initenv [... All extra params...] For the second command, this is simple, as it already runs as the www-data user, so I wouldn't have to use sudo. But for the first command, I'd have to use sudo and add www-data to the sudoers file. I was wondering if this is a good idea, and how to do it in that case. Reading the manpage has left me with more doubts than certainties about this. This webserver would only be accessible from our internal network, by the way. The OS is Ubuntu Server 10.04.

• Texture and Pattern Generator

  - by Ara

  I use Adobe Fireworks for its Texture and Pattern tools to make things like this: http://i.imgur.com/sci7Roc.png and then i copy-paste it to Flash Professional (Adobe) to use there. but fireworks is so slow and buggy is there a free or commercial software to do this simple Texture / Pattern thing easily? Texture (like the second image above) Patter and Texture (like the first one) Transparent Texture, so the background color would be visible instead of the white lines in second image The ability to copy and paste it (as PNG 32 or any alpha transparent image) so i don't have to save it first and then import it to flash * I Use Mac OS X 10.8.4 *

• Can somebody help me install this jBPM based workflow management suite?

  - by Eternal Saint

  1.Its a book Workflow Interface software available at sourceforge http://bookworkflowint.sourceforge.net/ Any instructions on installing and configuring it would be great especially in windows, however I can try Linux specific ones as well. I could not find any installation instructions. I posted this in stackoverflow by mistake and was directed here. 2.Can you guys suggest any good scanning/digitization workflow software (document imaging) that I can adopt to my scanner software? Infact even a simple one would do may be based on hotfolders. I just want to be able to track the uniqueid/barcode of the scanned book, its status so that its not scanned again. It books or manuscripts could be in millions page count. I thought of using some kind of generic bug tracking tool, just track a few fields, dont know if its the right choice Thank you very much

• Windows redirect traffic to different DNS name not fixed IP address (hosts file equivalent)

  - by Arik Raffael Funke

  Using the Windows hosts file, one can redirect traffic for a domain to a specific IP address, e.g. domainA.com -- 127.0.0.1 I am looking for a SIMPLE way to do the same, but for a target domain name not for a target IP address (as this is dynamic), I.e. domainA.com -- domainB.com Addition: After the getting some initial answers I think I need to concretise my question. Situation: I have an application which looks up the IP of the target domain via DNS and then connects via HTTP to the IP address. I do not have control over any proxy settings. Option 1 Basically I am looking for a way to: intercept DNS requests for a domainA.com launch a DNS request for a domainB.com serve the IP of domainB.com in response to the request for domainA.com Without running an entire DNS server. Option 2 If a DNS server is the only way, in the alternative I would also be happy with an solution to how to define a non-standard DNS-server for a single application. Any ideas for wrapper applications, etc?

• Redirect subdomain to hidden folder using mod_rewrite

  - by radious

  Hello! I want to keep my blog in subfolder domain_com/htdocs/blog and access it using blog.domain.com. I can obtain it using apache's mod_rewrite: RewriteEngine On RewriteBase / RewriteCond %{HTTP_HOST} ^blog\.domain\.com RewriteCond %{HTTP_HOST} !^/blog RewriteRule ^(.*)$ /blog/$1 [L] But I also want to redirect hxxp://domain.com/blog to hxxp://blog.domain.com (simply because I want to hide it from users). Simple redirection like: RewriteCond %{HTTP_HOST} ^wojtyniak\.com$ RewriteRule %{REQUEST_URI} ^/foo RewriteRule ^(.*)$ http://foo.wojtyniak.com [L,R=301] causes redirection loop. Is there any way to make such a redirection without loop? Big thanks! PS. Sorry for those hxxp thing, but serverfault thinks these are link and doesn't allow me to post more than one.

• How to execute files on LAN drives in a Windows Domain

  - by matnagel

  We have a very small LAN here, but some peolpe here think we need Active Directory, though nobody knows how to maintain it. I am not in the position to change this. How can I get full access (on Linux it would be "execute" rights) also for files on network drives (the files are just on another machine next room) My account is in the group Administrators on a windows 2003 server Domain Controller. I cannot open simple MS Access 2000 Databases or CHM Files from network drives in the lan How to do that? Some policy setting? I want to change that once. It is useless. We have no distinction between local or network files here. I would have to copy everything to a local drive and then do what I want.

• Software for formatting / web-publishing tutorial-type, technical articles

  - by gojira

  I want to put some of my own technical writing on the web: tutorials, how-to's, conceptual articles about programming etc. I write mostly for myself yet, but think others can benefit from it so I want to put it online, and I also have plans of making everything more coherent and turning it into a book. My articles are not meant as a blog, they're just meant as a collection of tutorials and how-to's, but I think a blog-type software would probably be the most appropriate mode of formatting that kind of stuff. Right now I am using the blog feature of cite u like, which is very low tech and I really need something better. On my wish list is, among other things: code snippets in scrollable boxes syntax highlighting for source code snippets tagging articles with graphical icons according to topic, like in slashdot of course users (i.e. readers) should be able to comment on articles Also, just more options than a super-simple blog should look slick! should not look wikipedia-like Is there any software you can recommend for this purpose?
